"Hunter and Sean are the real deal! My water heater crapped out suddenly on New Year’s Eve. I went to Angi and filled out the info and less than 10 minutes later, Hunter calls me! Told me he’d be out the next day….new year’s day!! Showed up when he said he would, diagnosed the issue quoted me a price and said he’d be there “tomorrow morning”. Showed up, just like he said he would for the price he quoted. Everything went well, and I wholly recommend Foothills Plumbing."

"I awoke to find no water pressure in any of the faucets and quickly realized the main water line to the house had failed and was flooding where it's attached at one of the walls of the house.  After quickly turning off the water main to the house, I searched Angie's list to find a reputable plumber in the area and found Mr. Rooter.  I was immediately able to reach somebody at Mr. Rooter who made a few calls and promptly called me back confirming that a plumber was en route (literally within an hour of calling).  Two trained plumbers (one with 30 years of experience) arrived as expected, and quickly diagnosed and fixed the problem.  They had all necessary parts with them on the truck and the problem was solved much faster than I expected.  Given that the house is in a rural area (holiday lake house), I was not expecting such quick and professional service.  I was totally impressed. Thanks Mr. Rooter.  You have a new long term customer!

"I had a water heater emergency on a Saturday, and my four girls were frantic with no hot water.  I called several plumbers who were not able to come out on the weekend or wanted way too much money.  When I called Steve at All about Plumbing, he was very nice and was able to come out the sameday.  He did not charge an estimate fee, gave me an estimate to fix the problem.  He installed a new heater that night and we were back in business and ready for Sunday morning showers before church.  He promised to be there at a certain time and was.  He was professional.  I would recommend to my friends and family."

"Stephen was great, my tub backed up with water and my toilet would not flush, turns out my septic field needed replacing. Very responsive, reasonably priced and best of all. I didn’t have to leave my home during the repairs. I’d give 10 stars if I could."

"We had another plumbing company come out due to a leak. Rather than do any diagnostics, they just replaced the pressure valve. It still leaked. I called the next Monday and was told oh, you need a new water heater. Johnny Gavilan from Preferred Home Services checked a couple things and found our expansion tank was bad. He did warn us there still could be a problem with the water heater but at least he checked first. If we need the water heater replaced, our expansion tank will be new!"

Water Heaters FAQs, answered by experts

Choosing between an electric water heater vs. a gas water heater comes down to personal preference. Overall, electric heaters are more energy efficient than their gas competitors. They’re also quieter to operate, take up less room, and don’t come with a risk of gas leaks. 

The downside is that electric water heaters cost more to operate than gas. They might also struggle to heat water fast enough for households that use large amounts of hot water. Lastly, a power outage could cause your electric water heater to stop working, whereas gas water heaters may still function.

Electric water heaters do not need an attached vent, but the location of the water heater should allow for roughly 12 inches of clearance around it. This allows cool air to flow around the appliance and allows repair technicians to work on its components safely. The exact amount of clearance space required depends on your local building codes.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

Yes, a heat pump water heater can work in colder climates but it’s much more effective where it’s warm. The reason is that the heat pump needs ambient warmth in the air to compress. The less warmth, the more compression required, thus using more electricity and offsetting the energy-efficient benefits.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.
